When the following com-
munication errors occur
between control board and
operation P.C. board:
• They transmit and receive
data that has nothing to
do with settings.
• They cannot transmit
and receive data each
other for about 2 seconds.
1. Connector CN10K, CN9S, CN5D on con-
trol board
5-pin wire to wire connector (hinge)
5-pin connector on operation P.C. board
Repair the
contact failure.
Keep the same operation
as the one before the
communication error has
occurred.
2. Trouble of control board and operation
P.C. board
Replace.
